    摘要： A process for manufacturing cumene by reacting propylene with benzene, including treating a vent stream from the reaction zone, to recover propylene for return to the reactor. The process involves using a gas separation membrane to separate propylene from propane in the reactor vent stream. The membrane separation step results in a residue stream typically containing as much as 30%, 40% or more propane, which is vented from the process, and a permeate stream containing 95% or less propylene, which is recirculated to the reactor.

    摘要： A process for manufacturing isopropyl alcohol by reacting propylene with a reagent, including treating a vent stream from the reaction zone, to recover propylene for return to the reactor. The process involves using a gas separation membrane to separate propylene from propane in the reactor vent stream. The membrane separation step results in a residue stream typically containing as much as 30% propane or more, which is vented from the process, and a permeate stream typically containing 95% or less propylene, which is recirculated to the reactor.

    摘要： A membrane hybrid process for treating organic-containing gas streams to remove or recover the organic. The process combines absorbent scrubbing, gas stripping, condensation, and membrane separation, and is particularly useful in treating high-volume, low-organic-concentration streams. The process may be operated such that the only products are a clean air stream suitable for venting to the atmosphere, and a small-volume, condensed liquid organic stream suitable to reuse or disposal.
